How we calculated this date
One row per rule, each showing its own input and what it did to the date. A step we could not verify says so instead of resolving itself.
| Step | Input | Date after this step | Confidence |
|---|---|---|---|
| Base term, 20 years from filing | Clock starts May 31, 2013, when application 13/907,791, the earliest non-provisional in its chain, was filed (this one was filed Feb 12, 2021); a parent in its chain could not be resolved (the next row) | May 31, 2033 | High confidence |
| Continuity chain | A reissue: its term follows the original patent's, with the original's term adjustment; a parent in the chain could not be resolved | dated from this application's own claim | Low confidence |
| Patent term adjustment | No term adjustment record on a grant after 2005, so none is added | no change | Medium confidence |
| Terminal disclaimer cap | None on record | no cap applied | High confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | The reissue's fees post to its original, whose fee record is not available (likely before 2001) | In force | Medium confidence |
| Computed term end | The steps above, in order | May 31, 2033 | Low confidence |

How we rank
Every date shows its work: the base term, any term adjustment or extension, any disclaimer cap, and the maintenance fee record, each with a confidence tier. How this record was built
Computed patent terms end on the dates shown. Related patents and pending applications may cover overlapping subject matter.
In force means the term is running and no lapse is on record. It is not a finding that the patent is valid.
